Reproductive parameters (number of eggs, fertility index, survival of juveniles) and the biochemical composition (proteins, carbohydrates, lipids) of Cherax quadricarinatus broodstock were examined in specimens with weights ranging from: (i) 30-45; (ii) 46-60; (iii) 61-75g; (iv) 76-90 g, in an intensive system (4 organisms/m2) with zero-water exchange (maintained at 28+1°C and aerated continuously). Better reproductive efficiency was observed in specimens with smaller weights. This effect was also reflected in the biochemical parameters of the eggs and juveniles. The use of broodstock whose weight ranges between 45 and 60g is recommended
